Problem 3P
Copper atoms have 29 protons in their nuclei. If the copper nucleus is a sphere with a diameter of 4.8 × 10−15 m, find the work required to bring an alpha particle (charge = +2e) from rest at infinity to the "surface" of the nucleus.

Problem 3P
Copper atoms have 29 protons in their nuclei. If the copper nucleus is a sphere with a diameter of 4.8 × 10−15 m, find the work required to bring an alpha particle (charge = +2e) from rest at infinity to the "surface" of the nucleus.
ANSWER:
Step 1 of 3
Here, we have to calculate the work required to bring an alpha particle from infinity to the surface of a copper nucleus.
The equation for the work done,
Where, - Electrostatic potential
- Charge of the particle
